Hotels: The venue is close to the city center, which means that numerous hotels are within walking distance or reachable by very short commute with bus/tram. The following two hotels are close to the venue:

  • Hotel Lorensberg (most speakers stay here)
  • Comfort Hotel Panorama

Gothenburg has a very good public transportation system, and cheaper hotels can be found further away from the city center. For example, in Mölndal one can find Quality hotel The Weaver (18 minutes by tram), Åby Hotel – Best Western Plus (25 minutes by tram), or Good Morning Mölndal (25 or 30 minutes by bus).

Getting around Gothenburg: To plan trips, it is useful to download the Västtrafik to Go app or browse You can buy a day card or 3 day card ticket on the app, or in most convenience stores (Pressbyrån or 7-eleven). These cards include travel by bus, tram and ferry within Gothenburg. Note that you cannot buy tickets by cash on buses or trams.

Getting to Gothenburg: If you fly to Gothenburg, you will arrive at „Landvetter“ airport.There are two options for getting to the city center:

  • You can take the Airport bus (Flygbussarna). It takes about 30 minutes, and there are several stops in the center. One of these stops is Korsvägen, which is 7min walking from Hotel Lorensberg. Only credit cards are accepted on the bus. For more information and the timetable visit
  • You can take a taxi. You will find a taxi stand at the airport. A trip to/from the city center costs approximately SEK 500. Service is included in the taximeter price, which means that tipping is not expected.
